The Brain's "I" Center: Understanding Sense of Self.
The anterior precuneus (aPCu) in the brain plays a critical role in forming our physical sense of self or “I”, as revealed by Stanford Medicine. The aPCu is part of a network of brain regions that integrate various types of bodily information to create our self-awareness. When activity in the aPCu is disrupted, people’s perceptions of their place in the world dramatically change, invoking feelings of depersonalization. The findings further our understanding of self-awareness and consciousness.
